please don't buy this product. No proper service. frequent software/hardware complaint. this is a fraudulant product from karbon. starts vibrating while attending a phone call and never stops until the phone is become switched off.
I brought this phone and repair 3 time in a weak but no result and change it once but all are same bad. That is - 1. Poor sound quality. 2. Missbehave of vibration. 3. Memory Card always not support. 4. Never send MMS if it use handset does not open, like as dead. 5. Very poor hardware. 6. Charging speed very very slow. 7. Headfone quality too bad to use. I think it is not prepair to use, its need development.
If you buy U think loss your money in lotery.
Never buy, Im fool to buy it.
I purchased Karbonn mobile on last week to test how the phone works with triple sim.I have observed some negatives.While receiving the incoming call some noise coming up to 10 seconds.Signal catching is very poor.Batter wont reach up to 2 days also,if we fully charged.It wont support the memory card more than 4GB.Video songs clarity is too bad.
